Yingying Ren

In contrast with the simplicity of making a Möbius strip, where one can take a paper strip and glue the ends together with one side flipped, creating a physical Klein bottle is usually much more complex. I present a Klein bottle constructed by weaving planar ribbons, much like the case for a Möbius strip. Thanks to the ribbons' in-plane curvature, I wove this Klein bottle following a regular tri-hexagonal pattern with no singularity, as indicated by the Klein bottle's topological properties. In the final structure, the neck of the bottle elegantly goes through a hexagonal gap without touching any other parts, exemplifying the balance between each ribbon's desire to remain planar and the complex force interactions in the woven assembly.
